Hi Jacob-san,

Thank you for your reply.

It seems user's guide of TPS65987EVM ($199) is identical with TPS65987-90EVM ($299).
Is it correct?
If the answer is yes, I understand schematic and BOM, function is the same however I can't catch the difference between these EVMs.
Why TPS65987-90EVM ($299) remains in existence if these EVMs are completely identical?

Best Regards,
Yaita

Hi Yaita-san,

There should be an update to the BOM. If you look at the top image of the PCB you will notice that there is a device that is DNP on the older version. I think the new User's Guide was not link to the new EVM. I will reach out to the team to correct this.

Hi Eric-san,

I found TPS65987-90EVM is deleted and there is TPS65987EVM only for EVM of TPS65987D.
However user's guide shows TPS65987-90.
http://www.ti.com/tool/tps65987evm

Is the user's guide for TPS65987EVM?

Hi Eric-san,

My customer got TPS65987EVM and there is J4 and J5, J6 as the following.

On the other hand, I think the TPS65987EVM doesn't match the following user's guide (page 3-4).
http://www.ti.com/lit/ug/slvubf3a/slvubf3a.pdf
Could you please look into it?

In addition, I would like to know what is jumper configuration of J6 for TPS65987EVM? (How to use J6?)

Best Regards,
Yaita

Hi Yaita-san,

The document is in the process of being updated. J6 is for the PPExternal path. This is unused on the TPS6587EVM since the two internal power paths are used instead.

Thanks,
Eric
